Overview

The 3PEAK TP5531/5532/5534 is a series of low-power chopper-stabilized operational amplifiers that provide input offset voltage correction for low offset and offset drift over time and temperature. The series operates with a single supply voltage as low as 1.8 V, while drawing a quiescent current of 42 μA per amplifier with a gain bandwidth product of 350 kHz. The series is unity-gain stable, and has no 1/f noise. It also has a good power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR), and features the rail-to-rail input and output swing.

The series is designed using an advanced CMOS process. The TP5531 (single version) is available in the SOT353 (SC70-5), SOT23-5, and SOP8 packages. The TP5532 (dual version) is offered in the MSOP8 and SOP8 packages. The TP5534 (quad version) is available in the TSSOP14 and SOP14 packages. All versions are specified for operation from −40°C to 125°C.
